\floatfoot{\footnotesize \textit{Notes.} Pop-up warning RD effect fits and point estimates by bandwidth for outcomes listed in panel titles. ``Full'': global quadratic. ``+/- 0.1'': local linear within 0.1 bandwidth. ``rdbwselect'': optimal bandwidth selection using \citet{calonico2014robust}. See  section \ref{sec:RD} for details.}
